PAPER-BAG MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,744, dated May 1, 1883.

Application filed January 29, 1879.

To all whom it may concern:

Be it known that I, QHARLES F. ANNAN, of

Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain Improvements in PaperBag Machines, of which .the following isa specification.

The object of my invention is to provide improved machinery for theconstruction of paper bags of a cornucopian shape.

Theinvention consists in the'im proved means, as hereinafter described and claimed, for attaining said object. p

In the accompanying drawings,.Figurel represents a top view of my machine; Fig. 2, a side elevation of same; Fig. 3, a section of one of the pairs of cutters Fig. at, a top view, showing the manner in which the edges of the strips are folded; Fig. 5, a section through the pastebox on line as m, Fig. 1; Fig. 6, a side view of thereciprocatingcutter which severs the strips into blanks; Fig. 7, a section on line 3 y, Fig. 6; Fig. 8, a view of the proximate ends and parts of one of the blanks severed therefrom Fig. 8, a section on line .90 m, Fig. 1. Fig. 9 represents one of the blanks after being severed from a strip. Fig. 10 represents a section of the folding mechanism on line a 2, Fig. 1. Fig. 11 shows one of the blanks with a dotted line indicating the direction of the fold. Fig. 12 represents a side view of one of the bags as it leaves the machine, and Fig. 13 a perspective view of the same after being opened.

Similar letters of reference indicate correspondin g parts throughout the different views. A represents the frame-work, cast in suitable shape to afford support for the various parts of the machine. At one end of said framework a removable mandrel or arbor, B, isjournaled, which carries the roll, r, of paper to be used in the construction of the bags. From said mandrel B the paper passes inwardly to rollerD, (journaled in said frame A,) and thence through the cutting apparatus to roll E. Said cutting apparatus consists of shafts 3 4, upon which are mounted disks 1 2, convexed on the sides opposite to those of interference and concaved on the sides of interference. Said disks are secured to their shafts in such manner that the relative positions of the pairs thereof may be changed as desired and the width of the strips of paper severed made to suit convenience. After the paper has been cut in proper ways bear against rolls passed over roll E, the edges of each section come in contact with a wheel or paste-roller, G, arranged in paste-box F. Said rollers Gr arejournaled in arms H, which are adapted to slide on the two rods I, (secured in said pastebox F,) and are fastened to one of the same by setscrews. In the course of manufacture the sheets of paper, when first severed by cutters 1. 2, are folded over at the edges by hand, and said folded edges lie flat upon the main body of the strips. After this has been once done the tension of the paper passing over roller E and through the rolls hereinafter described insures the continued folding of said strips. From the roller E the folded strips pass to the rolls J J and K K. The rolls J K are borne upon shaftsjournaledintheframeA,anddriven by a series ofappropriate cog-wheels connected with the main shaft of the machine. The rolls J K are journaled in yokes L, sliding on vertical posts M, said yokes being pressed down by springs 0, so that the rolls J K may al- J K, thereby insuring the carrying of the paper as desired. The first pair of rolls, J J, draw the paper over the rolls D E from the mandrel B and between the cutters 1 2. The rolls J K are provided with grooves P to receive the folded edges 8 of the strips of papers, and allow said strips to pass between them without removing the paste laid upon the folded edges of the same. These grooves P are formed by collars P on the rolls J K, and said collars P are preferably secured to said rolls by means of set-screws, so that the position of the grooves may be changed to correspond with theadjustment of the cutters l 2. 'As the strips 8 pass from between the rollers J J to the rolls K K they are cut in suitable lengths by a cutter, S. Said cutter S consists of a serrated knife having one side, a, in unison with its plane of movement, and the other side, I), at an acute angle therewith. Theedge oftheknifeis provided with V-shaped serrations 0, which are continued through the side I), so that a knife-edge is imparted to all parts of said serrations. Said cutter slides on ways set at an acnteangle to the strips 8 and attached to the frame A, and to its extremities are attached rods connected at their free ends withjointed arms These arms are in turn secured to a rock-shaft actuated (through any width by cutters 1 2, andjust as it is being desired means) by a cam carried by a shaft connected by a cog-wheel with the driving mechanism of the machine. the action of the cutter S may of course be regulated by changing the cog-wheels or the cam employed. The said cutterShasits guides 'or ways so arranged that the paper may be severed in close proximity to the rolls K K, whereby the paper is assuredly grasped by the latter rolls. After the strips 8 have been cut transversely by the cutter S and scalloped by the serrated edge thereof, they are carried forward by endless cords c c,which pass around grooves in said rolls K K and around pulleys d. Said pulleys d are secured in a frame-support set in frame A. After leaving the endless cords c the blanks are forced downwardly between the rolls 0 e by afolding-bladaf. Said rolls 0 e and the frame supporting the pulleys d are situated in the same plane, but at an angle of forty-five degrees with the rolls J K, and thereby-fold and fasten said blanks in angular shape, so that a cornucopian-shaped bag is formed, as desired. The rolls '6 e are driven in any desired manner by connection with the driving mechanism, and the folding-bladefis preferably driven by rods connected at their free ends with eccentrics borne by a shaft at like angle with rolls E E, and the latter bearing bevel-wheels connected with the driving mechanism.

Having thus described my invention, whatI claim is- 1. The method of making cornucopias or conical paper bags, the same consisting in cutting a web of paper into a series of longitudinal strips, folding over and applying paste to one edge of each strip, cutting the strips transversely into blanks, carrying the blanks forward in rows, and simultaneously folding a number of blanks diagonally to bring one edge The frequency of of each blank against the pasted edge of the same blank, as set forth.

2. The combination, with the diagonal rollcrs e c and folding-blade f, of the rollers K K, provided with grooves for the reception of cords c, the endless cords c, and pulleys (LV and diagonal frame carrying same, substantially as described, whereby the blanks are fed to the rollers c e and folded in shape for the cornucopias, as set forth.

3. The combination, with the rolls J J K K, of a cutter, S,havin g a serrated edge, one side, a, of which is in unison with its plane of motion, and the other side, 1), at an acute angle therewith, and provided with ways attached to frame A and set at an acute angle to the strips 8, substantially as described, whereby a serratedv or scalloped edge is given to the blanks, and at the same time the paper is divided in close proximity to the rolls K K, for the purposes set forth.

4. The paste-rollers and the arms in which they are journaled, combined with the pastebox having longitudinal rods to support the arms of the paste-rollers, as set forth.

5. In a machine for making paper bags, the combination, withguiding, feeding, folding, and delivery mechanism, of the adjustable rotating cutters, the adjustable paste-rollers, the feed-rollers having adjustable collars, and the transverse reciprocating cutter, whereby cornucopias or conical paper bags are formed of any desired size from a web of paper, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES F. ANNAN.
